Product Description
- Description
- The bq77908A is a battery protection and cell balancing device intended for Li-Ion and Li-Polymer battery packs. The bq77908A monitors 4- to 8-series individual cell voltages and provides fast-acting outputs that may be used to drive N-channel MOSFETs to interrupt the power path. Activation delays and recovery methods for safety conditions are fully programmable in non-volatile memory.
- Automatic cell balancing is provided using internal 50-mA cell circuits. A robust balancing algorithm ensures optimum performance by maintaining all cell voltages in balance. Balancing may be configured to operate at all times, only during charge, or can be disabled completely.
- Features
- • 4-, 5-, 6-, 7-, or 8-Series Cell Protection
- • Individual Cell-Voltage Monitoring
- • Low-Side NMOS FET Drive for Charge and Discharge Control
- • Compatible With 1-mΩ Current-Sense Resistor
- • Supply-Voltage Range From 5.6 V to 40 V
- • Integrated 3.3-V Micro-Power LDO Regulator
- • Low Supply Current
- – Normal Mode: 50 µA, Typical
- – Shutdown Mode, LDO OFF: 5 µA, Typical
- • 38-Pin TSSOP Package
- • Internal 50-mA Automatic Cell Balancing
- Applications
